Back in December of 2023 my fiancé and I bought a 2BR condo in our hometown of Chicago (We currently live in Texas). We planned for my MIL to live there because her current landlord was raising rent every year. We pay about $1,700 (mortgage + HOA's) every month, and my MIL gives us $1,000. Is this considered rental income? Or is there another way this is classified. Also, my fiancé and I plan on getting married this November, so we will be filling jointly (don't know if this changes anything). Any insight would help, TIA.
